Abstract

The effect of ground replacement on control of underground vibrations and differential settlement of structures G. Rosenhouse, F. Kirzhner and Y. Zimmels Faculty of Civil and Environmental Engineering - Technion, Israel Institute of Technology, Israel Abstract Foundations design considers ground properties in their natural state. However, the ground over which the foundation is based may be too hard or non-uniform. In the first case it might transfer too much vibration, and in the other case it can lead to differential settlements and lack of stability. A possible way of controlling vibrations radiation caused by machines, vehicles and trains and isolating structural vibrations is replacement of the original ground by layers of elastic media. The isolation of vibration amplitudes should be kept within the limits specified in standards, at the control points. Control of structural deflections can help in reducing or eliminating differential settlements and instabilities, which cause damage to s
